“…In various crop systems, different zoophytophagous species naturally colonize the plants (Albajes and Alomar, 1999;Montserrat et al, 2000;Alomar et al, 2002). For instance, Dicyphus maroccanus and N. tenuis are both present on tomato plants in eastern Spain (Salas Gervassio et al, 2017). However, N. tenuis tends to displace D. maroccanus from plants because of higher competitive abilities.…”

Zoophytophagy (true omnivory) is a ubiquitous behavior. It allows plant-feeding predators to maximize their development by finding essential nutrients, and to survive when animal resources are scarce. In agroecosystems, some zoophytophagous predators are highly efficient biological control agents. However, when feeding on plants, they can generate crop damage that reduce grower's interest in these predators. Artificial selection on behavioral traits of candidate zoophytophagous predators could improve the ecosystem services they provide. Thus, a zoophytophagous species considered as noxious may become an adequate biocontrol agent, following a selection process. Numerous theoretical and applied aspects should be considered during the selection process for the breeding of desired individuals. This review focuses on the potential of the evolutionary approach to optimize the biological control services provided by plant-feeding predators-or zoophytophagous predators-and discuss some ecological and biological control consequences as well as the limitations of the approach.

“…The mean survival of N. tenuis was lower than that of D. cerastii or M. pygmaeus nymphs. Salas Gervassio et al (2017) found a different result in the Dicyphus maroccanus Wagner– N. tenuis system; D. maroccanus females preyed on N. tenuis first instars in fewer than 5% of cases, but N. tenuis females killed D. maroccanus first instars in 30% of cases.…”

“…Indirect competition can be more important than direct interactions between mirid species. Salas Gervassio et al (2017) reported that N. tenuis can be a better competitor than other species of mirids, describing its greater capacity to obtain food and reach larger population sizes compared to other mirids in eastern Spain tomato crops. Michaelides et al (2017) also found that N. tenuis is a better competitor than M. pygmaeus when feeding on T. absoluta eggs, so it is possible that D. cerastii may also be outcompeted by N. tenuis .…”

“…Intraguild predation is symmetrical if similar levels of predation occur between the two species, or asymmetrical if one tends to prey more than the other (Lucas et al, 1998;Lucas, 2005). Intraguild predation is pervasive among generalist predators (Polis et al, 1989;Lucas, 2005), and has been reported for Dicyphini species that share the same plant host (Moreno-Ripoll et al, 2012;Perdikis et al, 2014;Salas Gervassio et al, 2017).…”

Dicyphine mirids are one of the most important groups of predators on tomato. In the Mediterranean region, several species in the genera Dicyphus, Macrolophus, and Nesidiocoris (Hemiptera: Miridae, Bryocorinae, Dicyphini) colonize protected horticultural crops. In Portugal, Nesidiocoris tenuis (Reuter) is increasingly abundant in the mirid species complex of tomato crops and appears to be displacing the native Dicyphus cerastii Wagner. In order to know whether intraguild predation (IGP) can explain the decreasing abundance of D. cerastii, we evaluated predatory interactions between adult females and first instars of D. cerastii vs. N. tenuis but also D. cerastii vs. Macrolophus pygmaeus (Rambur), as this species is also naturally present in horticultural crops in Portugal. Cannibalistic interactions were also tested for the same three species. All experiments were performed under laboratory conditions, in Petri dish arenas, in the presence or absence of Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) eggs as alternative prey. Predation on both heterospecific and conspecific nymphs occurred only in the absence of alternative food. Intraguild predation was mutual and symmetrical between D. cerastii and M. pygmaeus. However, IGP was asymmetrical between D. cerastii and N. tenuis, favouring the first. Cannibalism was not significantly different among these mirid species. Our results show that D. cerastii has a greater capacity to feed on intraguild prey than N. tenuis. Therefore, IGP on small nymphs does not explain the abundance shift between D. cerastii and N. tenuis.

“…Verder moet er rekening mee worden gehouden dat N. tenuis warmte minnend is en bij hogere temperaturen zich nog steeds sneller kan ontwikkelen dan andere soorten. Recent is bij een competitieproef tussen N. tenuis en D. bolivari in tomaat gevonden dat ondanks het negatieve effect van D. bolivari op de ontwikkeling van N. tenuis, de populatiegroei van N. tenuis bij 25°C nog steeds veel groter is dan bij D. bolivari(Salas Gervassio et al 2016).Opvallend was dat in onze studie M. pygmaeus in het laboratorium géén effect had op N. tenuis, zowel met al zonder alternatief voedsel. Dit geeft aan dat deze roofwants minder agressief is dan de andere soorten en is een bevestiging van eerdere studies(Moreno-Ripoll et al 2012).…”

Effecten van omnivore roofwantsen op plagen in gerbera, tomaat en roos en de risico's op bloem-en vruchtschade Omnivorous predators of the Miridae family feed both on plant and prey. This ability is a huge advantage for establishment into crops when pests are absent or scarce, but at the same time a risk when through plant feeding fruit and flowers get damaged. In this project we evaluated the potential for pest control with mirid predators in gerbera, rose and tomato crops. Pest control was assessed for whiteflies (gerbera and tomato), Echinothrips (gerbera and rose), Tuta absoluta (tomato), The Tomato Looper (gerbera and tomato) andNesidiocoris tenuis (tomato). In gerbera and tomato, not only pest control, but also the level of crop damage these mirids can cause was assessed. Finally, methods to enhance establishment were evaluated. AbstractOmnivore roofwantsen van de familie Miridae hebben de bijzondere eigenschap dat ze zowel van plantmateriaal als van prooien kunnen leven. Dit brede voedselmenu heeft enorme voordelen voor de biologische bestrijding, omdat ze daardoor verschillende plaagsoorten kunnen bestrijden en tegelijkertijd preventief ingezet kunnen worden doordat ze zich voeden met plantsappen en/of alternatief voedsel. Dit voordeel van plantenvoeding is tegelijkertijd een nadeel, omdat de wantsen ook schade kunnen geven aan bloemen en vruchten. In dit project is de potentie voor plaagbestrijding met een aantal soorten omnivore roofwantsen onderzocht in gerbera, roos en tomaat. De plaagbestrijding was gericht op wittevlieg (gerbera en tomaat), Echinothrips (roos en gerbera), Tuta absoluta (tomaat), Turkse mot (gerbera en tomaat) en Nesidiocoris tenuis (tomaat). Daarnaast hebben we gekeken naar de schade die ze kunnen veroorzaken in gerbera en tomaat en is gekeken naar methoden om vestiging te verbeteren.Stichting Wageningen Research.
